Pankhani ya-kulongedza kwambiri ndi kusindikiza kusindikiza, kupeza ndi kusunga kachulukidwe kamitundu nthawi zonse ndizovuta komanso chizindikiro chaubwino. Mapangidwe a inki ndi kujambula kwa silinda ndi mbali zofunika kwambiri za njirayi, koma mankhwala osindikizira a rotogravure ndi nyenyezi yeniyeni. Gawo lofunikali musanasindikizidwe ndizomwe zimatsimikizira kuti inkiyo imamatira mofanana, zomwe zikutanthauza kuti kuthamanga kulikonse kudzakhala ndi mitundu yofanana, yowala yomwe imakhala yosavuta kuneneratu ndi kubwereza. Mochulukirachulukira, atsogoleri amakampani akuzindikira kuti kuyika ndalama pamankhwala olondola a pamwamba pa ma silinda a rotogravure sikuli koyenera koma ndikofunikira kuti pakhale mpikisano, zomwe zimakhudza mwachindunji momwe anthu amawonera chizindikirocho ndikuchepetsa zinyalala.
Momwe Mphamvu Zapamwamba Zimakhudzira Kumata kwa Inki
Lingaliro loyambirira la kusindikiza kwa rotogravure ndikusuntha inki kuchokera ku maselo ang'onoang'ono ojambulidwa mu silinda kupita ku gawo lapansi, zomwe nthawi zambiri zimakhala zosinthika monga pepala, filimu, kapena zojambulazo. Kachulukidwe ka mtundu, kapena kuti filimu ya inki yosindikizidwa ndi yolemera komanso yosaoneka bwino, imadalira kwambiri momwe inkiyo imatuluka bwino komanso molingana ndi ma cellwa ndikumamatira pamwamba pa gawo lapansi.
Sayansi ya Momwe Masamba Amanyowa
Kunyowa kwa gawo lapansi kumatsimikiziridwa ndi mphamvu yake pamwamba, yomwe imayesedwa mu dynes/cm. Zida zokhala ndi mphamvu zochepa, monga polyethylene (PE) kapena mafilimu a polypropylene (PP), mwachibadwa zimakhala za hydrophobic ndi oleophobic, zomwe zikutanthauza kuti sizimamatira ku inki wamba. Ngati pamwamba sichikuchitidwa bwino, inki imakhazikika ndikutulutsa madontho, zomwe zingayambitse mapini, kubisala kosiyana, komanso kuchulukana kwamitundu komwe sikufanana. Musanayambe{{3}kusindikiza, ntchito yaikulu ya rotogravure cylinder surface treatment ndi kusintha ndi kulinganiza mphamvu ya pamwamba pa gawo lapansi kukhala mulingo waukulu kuposa kupanikizika kwa inki. Izi zimalola inki "kunyowa" kwathunthu ndikupanga zokutira mosalekeza, wandiweyani.
Njira Zazikulu Zothandizira Pamwamba pa Mapulogalamu a Rotogravure
Umisiri wambiri-odziwika bwino umagwiritsidwa ntchito kuyatsa malo apansipansi. Chosankhacho chimadalira pa zinthu, momwe zimasindikizira mofulumira komanso momwe ziyenera kugwirira ntchito.
Muyezo wa Makampani a Corona Discharge Treatment
Njira yodziwika kwambiri ndi corona treatment ya rotogravure printing, yomwe imatumiza -voltage electronic discharge (corona) yochuluka kupyola mugawo laling'ono laling'ono lisanafike pamalo osindikizira. Izi zimatulutsa mpweya, zomwe zimapanga ozone ndi plasma zomwe zimakhala ndi okosijeni pamwamba pa chinthucho, kukupatsani mphamvu zambiri ndikupangitsa kuti inki ikhale yosavuta. Zimagwira ntchito bwino kwambiri popeza kukhazikika kwa inki kosalekeza pamakanema ndi mapepala ambiri a polyolefin, zomwe zimatsogolera pakuchulukira kwamtundu wokhazikika.
Chemical Primers ndi Flame Chithandizo
Kusamalira malawi (pogwiritsa ntchito malawi oyendetsedwa ndi gasi) kapena chowonda chaching'ono cha mankhwala atha kugwiritsidwa ntchito m'malo mwa njira zina, monga kuchitira movutira{-kuchiritsa ma polima kapena kusindikiza{2}kusindikiza{3}}zotengera zitatuzikulu pogwiritsa ntchito rotogravure. Njirazi zimakwezanso mphamvu yapamtunda ndikuthandizira kuti zinthu zizigwirizana, zomwe zimapangitsa kuti kachulukidwe kamtundu wa gravure ukhale wokhazikika komanso wodziwikiratu.
Zimakhudza mwachindunji ubwino wa kusindikiza ndi kusasinthasintha kwa mtundu wa kachulukidwe
Sizingatheke kukokomeza momwe chithandizo chapamwamba chapamwamba chikugwirizanirana kwambiri ndi kusindikizidwa komalizidwa. Kusamalidwa kosagwirizana kumayambitsa zolakwika zosindikiza zomwe zimawoneka ngati kusintha kwa kachulukidwe.
Kuchotsa zovuta zosindikiza zomwe wamba
Ngati musamalira bwino pamwamba, mavuto monga kukanidwa kwa inki, kung'ung'udza (kuoneka kwamtambo kapena kowoneka bwino), ndi msampha woyipa (kumamatira filimu ya inki yonyowa ku ina) zatsala pang'ono kutha. Kuchiza pamwamba kumapangitsa kuwonetsetsa kuti filimu ya inki yomwe imayikidwa pansi imakhala yosalekeza komanso yofanana kwambiri poletsa mavutowa. Kusasinthika kumeneku ndi kutanthauza kukhala ndi kachulukidwe kamitundu pa intaneti komanso kuchokera ku roll kupita ku roll, zomwe ndizofunikira kwambiri pazithunzi zapamwamba-zojambula ndi mitundu yamtundu.
Kupanga kupanga mwachangu komanso moyenera
Makina osindikizira amakono a rotogravure amagwira ntchito mothamanga kwambiri. Osindikiza amatha kusunga liwiroli popanda kutaya khalidwe chifukwa cha njira yamphamvu komanso yosasinthasintha ya mankhwala. Imachepetsa nthawi yosindikizira kuti isinthe, imachepetsa zinyalala za inki pokonzanso, ndipo imapangitsa kupanga bwino kwambiri, ndikuwonetsetsa kuti kachulukidwe kake kakufunika pashelufu.
Njira zabwino kwambiri ndikuphatikiza ukadaulo kuti mupeze zotsatira zabwino
Kuti mukhale ofananira bwino, muyenera zambiri kuposa kungoyika gawo lamankhwala; muyenera kuganizira za ndondomekoyi.
Kuwongolera Ubwino ndi Kuwunika
Ndikofunika kwambiri kuyang'anitsitsa mlingo wa chithandizo nthawi zonse. Pofuna kukonza kachulukidwe wamitundu pamapaketi osindikizira, zolembera za dyne kapena zida zapamwamba kwambiri zapaintaneti-zoyesa zimagwiritsidwa ntchito kuwonetsetsa kuti mphamvu yapamtunda ili m'njira yoyenera, yomwe nthawi zambiri imakhala 6-10 dynes/cm pamwamba pa kulimba kwa inki. Machitidwe ophatikizika owongolera amatha kulumikiza mphamvu yamankhwala kuti akanikizire liwiro ndikupanga zosintha zokha kuti mulingo wamankhwala ukhale wofanana.
Synergy ndi Engraving pa Cylinders
Kuchita bwino kwa chithandizo chapamwamba cha masilindala a rotogravure kumagwira ntchito bwino pamene masilinda alembedwa mosamala kwambiri. Malo omwe agwiritsidwa ntchito bwino amalola inki kuchoka m'maselo opangidwa bwino popanda vuto lililonse. Akagwiritsidwa ntchito limodzi, amapanga kuphatikiza kwabwino kwambiri kwa kusindikiza kwa gravure chifukwa amakupatsirani zolimba zakuya, ma halftones akuthwa kwambiri, komanso kuchuluka kwamtundu wokhazikika.
Malingaliro Omaliza
Rotogravure printing surface treatment ndi njira yoyambira yomwe imathandiza kukwaniritsa kusindikiza kwangwiro. Ndilo chiyanjano chofunikira kwambiri pakati pa silinda yovuta ndi gawo lapansi lovuta. Zimapangitsa kuti zikhale zotheka kupeza kachulukidwe kamitundu kofananira komwe ma brand ndi makasitomala amafuna. Pamene bizinesi yonyamula katundu ikusintha ndi zipangizo zatsopano komanso kukakamizidwa kuti mukhale okonda zachilengedwe, matekinoloje atsopano a mankhwala apamwamba monga plasma ya mumlengalenga adzapitirizabe kukhala patsogolo. Ngati osindikiza ndi otembenuza akufuna kukhala opambana kwambiri pazabwino, liwiro, ndi kulondola kwa mtundu, akuyenera kupanga -sitejiyi yofunikayi kukhala yofunika kwambiri ndikuipangitsa kuti ikhale yogwira mtima momwe angathere. Tsogolo lapamwamba-zosindikiza za rotogravure zimadalira malingaliro atsopano ndikugwiritsa ntchito mosamala sayansi yotsegulira pamwamba.
